Papal Palace of Castel Gandolfo

The Papal Palace of Castel Gandolfo is the Pope's summer residence, located in the city of Castel Gandolfo, 16 miles southeast of Rome, Italy. The castle was acquired by the Vatican in 1596 when the Savelli family, who owned it, were unable to pay a debt to the Papacy. The Palace was made an extraterritorial property of the Vatican City under the 1929 Lateran Treaty, and it became a museum on 21 October 2016.
